Be it knownthat l, lhminion l1. BEASLEY,

a resident ol Gordon, in the county of lionston and S1 ate ot' Alabama,have invented certain new and useful lmproven'ients in Stump-PullingApparatus; and I do hereby declare'the following to be a full, clear,and exact description of the invent on, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to improvements in stump pulling apparatus, and theinvention consists in certain novel features of construction andcombinations and arrangements of parts as will be more fully hereinafterdescribed and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view illustrating myimprovements in operation. Fig. 2 is a perspective view of the stumpengaging device. Figs. 3 and 4 are views of details of construction, andFig. 5 is a view oi'a modification.

1 represents a stump to be drawn and 2 is my improved lever. The lever 2is made with a curved jaw 3 at one end and the jaw is toothed at bothsides, as shown, and may be used in the position shown, or may bereversed to bring the concave of the j aw against the stump. The jaw ispivoted in an elongated slot on a curved dog 4, by means of a pin 5 andthe jaw is provided with a series of pin receiving openings 6 to receivethe pin in any of them according to the leverage desired. The dog 4 hasa shar tong 7 at one end to engage the stump, an is made with a hook 8at its other end to receive one end of a chain 9 to be passed around thestump and secured to the other end of the dog. Two means are shown tosecure the chain to the dog so that one may. be employed in the event ofinjur to the other. One means for securing the c min is to provide thedog'with an integral fork 10 to hold the linksagainst movement. toothedbar 11 ivotally secured to the-dog by a bolt 12. 's bar is adapted toreceive any'link of the chain, and is rovided with a' nut 13.110 beplaced on the ar backnf'the chain and hold the chain against escape byreason of the nut catching in the teeth of the bar. Instead of having aslotted-dog to receive the jaw of the lever, I may bifurcate the. leverto receive the dog therein, as shown-in' Fig. 3.

The lever is provided with loops l4 at its The other means comprises ,a'

side to receive a long bar or arm 15, orit may have a socket to receivethe bar or arm.

The out r end of thisbar orarm has a represents a frame supporting ahorizontal shaft-2i, on which a gear 213 is secured and driven by apinion 223 connected with any engine or any source of power; On theshaft 2]. at both sides of the gear 22 my improved drums 19 are looselymounted on shaft 21 and adapted to be connected with the gear 22 bymeans of clutches 24 whereby the drums and gear will be caused to turntogether, and these drums are moved by levers 26 into or out of lockedengagement with the gear.

Both drums are constructed alike and the hereinafter description of onewill apply alike to both.

The drum is in the nature of a duplex or differential drum, having twocontinuous spirals 27 and 138 for the cable. The inner spiral 27 is ofsubstantially the same diameter throughout and the outer spiral 28 whileof greater diameter throughout than the spiral 27 is of least diameter,at its center and increases in diameter to its ends.

The cable 18 is secured at its ends to the ends of the drum and we willassume is wound on the smailer spiral -27. When the drum is, turned inone direction it. will wind on the larger 5 iral as it is fed from thesmaller and as it wil be taken up faster than it is fed from the drum,the looped portion of the cable will be drawn up to operatethe stumpengaging means above described to first twist the stump and then-pull itout of the ground. By turning the drum in the o posite direction, thecable Will be fed oti' t e larger spiraland onto the smaller and hencelet out the cable. ready for the next operation. It will also be seenthat as the outer spiral diminishes to the center it will.

have its greatest-power or lever e at this point-which will be when pullis esired -on the-stump to draw it out of the ground.

By haying two drums, one may be operrated to draw a stump while theother is being turned-to feed out its cable, and thus save considerabletime.

A great many slight changes might be LII I consisting of two spira eterthan the ot-herand both adapted to wind made in the general form andarrangement of the parts described without departing from my inventionand. hence I would have it understood that I do not restrict myself tothe precise details set forth but consider myself i at liberty to makesuch slight changes and alterations as fairly fall within the spiritand. sco e of my invention.

aving fully described my invention what I claim as nrw and desire tosecure by Letters-Patent, is 1. A drum for stu'm pullers and the like, ls one of greater dia1ncable thereon or therefrom;

2. -A drum for stum pullers and the like, consisting of two spira s, onelarger than the other and of smallest diameter at its center a cablesecured at its ends to the-drum and adapted to ,Windfrom one s iral ontothe otherto shorten or lengthen t e loop of the cable.

4. In astump bination with a shaft, a gear fixed thereto, and means forturning the shaft, of differen; tial or du lex drums loose on the shaftat opposite si es of the gear, clutches to lock either or both drums tothe. gear, levers .to
